Stealth R/T V6-2972cc 3.0L DOHC (1991)
Idle Speed: Adjustments
IDLE SPEED INSPECTION
NOTE:
a.
Adjustment of the idle speed is usually unnecessary. Idle speed on fuel injected vehicles is controlled by the MPI Control Unit through the Idle
Speed Control Servo.
b.
NEW FOR 1991: On Canadian models vehicles, the head lights, tail lights remain lit even after the headlight switch has been turned off. This is
caused by the Daytime Running Light circuit, and does not indicate a problem.
Before starting the Inspection or Adjustment Procedures, be sure:
^
Engine coolant temperature has reached 80-95~C (176-205~F)
^
Lights, engine cooling fan, and electrical accessories are OFF
^
Transaxle is in NEUTRAL or PARK
^
Steering wheel is at a center position (power steering equipped vehicles)
^
Parking brake is applied.
^
Verify the ignition timing is set to 15~ BTDC @ 700 +/- 100 RPM.
